BASIC ELECTRICAL PRACTICE - Quiz

1) What is the effect of the parallel circuit with one branch opened?

Current will remain same Whole circuit will not function No current will flow in that branch Voltage drop increase in the opened branch

2) What is the unit of resistivity?

ohm / cm ohm / cm² ohm - metre ohm / metre

3) Which type of resistor is used for Arc quenching protection in circuit breakers?

Varistors Sensistors Thermistors Light dependent resistor (LDR)

4) Which is the application of series circuit?

Voltmeter connection Lighting circuits in home Shunt resistor in ammeter Multiplier resistor of a voltmeter

5) What is the effect on opened resistor in series circuit?

No effect in opened resistor Full circuit current will flow in opened resistor Total supply voltage will appear across the opened resistor No voltage will appear across the opened resistor
