1. If the voltage is 12 V and the resistance in the wire is 3 Ω, what is the the current in the circuit?

Explanation

According to Ohm's law, the current in a circuit is equal to the voltage divided by the resistance. In this case, the voltage is given as 12 V and the resistance is given as 3 Ω. Therefore, the current in the circuit can be calculated as 12 V / 3 Ω = 4 A.

2. If the resistance in the circuit is 10 Ω and the current is 3 A, what is the voltage of the battery?

Explanation

The voltage of the battery can be calculated using Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). In this case, the current is given as 3 A and the resistance is given as 10 Ω. Therefore, the voltage of the battery can be calculated as V = I * R = 3 A * 10 Ω = 30 V.

3. If you connect a wire with 18 Ω of resistance to a batter, and measure the current to be 10 A, what is the voltage of the battery?

Explanation

The voltage of the battery can be calculated using Ohm's Law, which states that voltage is equal to current multiplied by resistance. In this case, the resistance is given as 18 Ω and the current is measured to be 10 A. Therefore, the voltage of the battery can be calculated as 10 A multiplied by 18 Ω, which equals 180 V.

Submit
4. If the current equals to 14 A and the resistance is 3 Ω, what is the voltage of the battery?

Explanation

The voltage of the battery can be calculated using Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R). In this case, the current is given as 14 A and the resistance is 3 Ω. Therefore, the voltage can be calculated as V = 14 A * 3 Ω = 42 V.

5. What is the resistance in the circuit that is connected to a 63 V battery,  and is measured to have a current of 9 A.

Explanation

The resistance in the circuit can be calculated using Ohm's Law, which states that resistance is equal to voltage divided by current. In this case, the voltage is given as 63 V and the current is given as 9 A. Therefore, the resistance can be calculated as 63 V / 9 A = 7 Ω.

Submit
6. If you connect a 7 V battery to a wire and measure the current to be 2 A, what is the resistance of that wire?

Explanation

The resistance of a wire can be calculated using Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). In this case, the voltage is given as 7 V and the current is given as 2 A. By dividing 7 V by 2 A, we get a resistance of 3.5 Ω.

Submit
7. If the voltage of the battery is 5 V and the resistance in the circuit  is 2.5 Ω. What is the current?

Explanation

The current in a circuit can be calculated using Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). In this case, the voltage of the battery is 5 V and the resistance is 2.5 Ω. Therefore, the current can be calculated as 5 V divided by 2.5 Ω, which equals 2 A.
