In a series circuit, what happens to the total resistance when more resistors are added?

• Increases

• Decreases

• Becomes zero

• Remains the same

According to Kirchhoff's Current Law (KCL), at any node in a circuit:

• The sum of voltages must equal zero

• The sum of all currents entering equals the sum of all currents leaving

• The current remains constant

• The voltage remains constant

A Zener diode is primarily used for:

• Halved

• Doubled

• Becomes zero

In a parallel circuit, the total current is:

• Equal to the largest branch current

• Sum of all branch currents

• Average of all branch currents

A transistor can be used as:

• Reverse bias region

• Cut-off region

• Saturation region

The efficiency of a half-wave rectifier compared to a full-wave rectifier is:
