What is (void*)0?
- Representation of NULL pointer
- Error
- Representation of void pointer
- None of above
Correct Answer

A. Representation of NULL pointer

Explanation

(void*)0 is the representation of a NULL pointer. In C and C++, a NULL pointer is a pointer that does not point to any memory location. It is often used to indicate the absence of a valid pointer value. The (void*)0 notation is used to explicitly cast the value 0 to a void pointer type. This is done to indicate that the pointer does not have a specific type associated with it, allowing it to be assigned to pointers of any type. Therefore, (void*)0 is the correct answer as it represents a NULL pointer.

If series current doubles, then:
- Voltage is doubled
- Resistance is halved
- Voltage is reduced
- Resistance is doubled
Correct Answer

A. Resistance is halved

Explanation

When the series current doubles, it means that more current is flowing through the circuit. According to Ohm's Law (V = IR), the voltage (V) across a resistor is directly proportional to the current (I) flowing through it. Therefore, if the current doubles, the voltage across the resistor will also double. On the other hand, the resistance (R) in the circuit is inversely proportional to the current. So, if the current doubles, the resistance will be halved.
