    What is the unit for resistance?

    • Volts

    • Amperes

    • Ohms

    • Joules

    Correct Answer
    A. Ohms
    Explanation
    The unit for resistance is ohms. Ohms is the standard unit of measurement for electrical resistance. It is named after the German physicist Georg Simon Ohm, who formulated Ohm's law, which relates the current flowing through a conductor to the voltage applied across it and the resistance of the conductor. The unit ohm is represented by the symbol Ω.

    What is the unit for current?

    • Volts

    • Amperes

    • Ohms

    • Joules

    Correct Answer
    A. Amperes
    Explanation
    The unit for current is amperes. Amperes, symbolized by A, is the standard unit for measuring electric current. It represents the flow of electric charge in a circuit. Volts, ohms, and joules are units for voltage, resistance, and energy respectively, and are not used to measure current.

    What is the unit for voltage?

    • Volts

    • Amperes

    • Ohms

    • Joules

    Correct Answer
    A. Volts
    Explanation
    The unit for voltage is volts. Voltage is a measure of the electric potential difference between two points in a circuit. It represents the force or pressure of the electric charges flowing through the circuit. The volt is named after the Italian physicist Alessandro Volta, who invented the first battery.

    In the picture, how resistance is connacted? - ProProfs

    In the picture, how resistance is connacted?

    • In series

    • In parallel

    • They are not connected

    Correct Answer
    A. In parallel
    Explanation
    The correct answer is "in parallel." In a parallel circuit, the resistors are connected side by side, allowing multiple paths for the current to flow. This means that the total resistance of the circuit decreases, as the current can divide and flow through each resistor independently. Therefore, in this picture, the resistors are connected in parallel, providing multiple paths for the current to pass through.

    Which of these is the equation for current divider?

    • I2= (R1/R1+R2) * l

    • V = IR

    • R = IV

    • PE = mgh

    Correct Answer
    A. I2= (R1/R1+R2) * l
    Explanation
    The equation I2= (R1/R1+R2) * l represents the current divider formula. This formula is used to calculate the current flowing through a specific resistor (I2) when a current (l) is divided between two resistors (R1 and R2) connected in parallel. The formula takes into account the individual resistance values (R1 and R2) and the total resistance (R1+R2) to determine the proportion of current flowing through the second resistor (I2).

    How can measurment the voltage divider in the circuit? - ProProfs

    How can measurment the voltage divider in the circuit?

    • Series

    • Parallel

    • None of them

    Correct Answer
    A. Series
    Explanation
    The correct answer is "series." In a voltage divider circuit, the resistors are connected in series. This means that the current flowing through both resistors is the same, and the voltage across each resistor is proportional to its resistance. By measuring the voltage across each resistor, we can determine the voltage drop across the entire circuit and calculate the output voltage.

    What is shown in this picture?

    • Resistors connected in parallel

    • Batteries connected in parallel

    • Resistors connected in series

    • Batteries connected in series

    Correct Answer
    A. Resistors connected in series
    Explanation
    The picture shows resistors connected in series. In a series circuit, the resistors are connected end to end, forming a single pathway for the current to flow. The current passing through each resistor is the same, and the total resistance of the circuit is the sum of the individual resistances.

    In this circuit diagram, what are R1, R2, and R3? - ProProfs

    In this circuit diagram, what are R1, R2, and R3?

    • Batteries connected in series

    • Batteries connected in parallel

    • Resistors connected in series

    • Resistors connected in parallel

    Correct Answer
    A. Resistors connected in parallel
    Explanation
    The correct answer is resistors connected in parallel. In a parallel circuit, the resistors are connected in such a way that the current has multiple paths to flow through. This means that the voltage across each resistor is the same, while the total current is divided among the resistors. This configuration is commonly used when the goal is to decrease the overall resistance in a circuit.

     if you have R1=10kohm and R2=50kohmand the source of current is 10A,how can  find  each current of R1 and R2 ?

    • I1=8A, I2=6A

    • I1=1A, I2=3A

    • I1=8.3A, I2=1.6A

    • None of them

    Correct Answer
    A. I1=8.3A, I2=1.6A
    Explanation
    Based on the given values of resistance (R1=10kohm, R2=50kohm) and the source current (10A), we can use Ohm's Law (V=IR) to find the voltage across each resistor. The voltage across R1 can be calculated as V1=I*R1=10A*10kohm=100kV. Similarly, the voltage across R2 can be calculated as V2=I*R2=10A*50kohm=500kV. Since the current passing through each resistor is equal to the voltage across it divided by its resistance (I=V/R), we can find the currents as I1=V1/R1=100kV/10kohm=10A and I2=V2/R2=500kV/50kohm=10A. However, the given answer of I1=8.3A and I2=1.6A does not match the calculated values, so the correct answer is none of them.
