For a given voltage, four heating coils will produce maximum heat, when connected

Detailed Solution: Question 4

Maximum heat produced is

for P to be maximum, Req should be minimum which is minimum of all four coils are connected in parallel.

Given figure shows a plot of d.c. voltage applied to a resistor of 5 Ω for 15 seconds. The total energy consumed by the resistor is

Detailed Solution: Question 5

energy = power x time

Hence, the heat consumed by the resistor

= 1140 J

The charge in a capacitor is given by

 

if the voltage across this capacitor be v(t) = sin t, the current i(t) through the capacitor is

Detailed Solution: Question 6

The current through.the capacitor is 

Test: Basic & Electric Circuits- 1 - Question 7

The unit of reactive power is

Detailed Solution: Question 7

Active power does do work, so it is the real axis. The unit for power is the watt (symbol: W). Apparent power is often expressed in volt-amperes (VA) since it is the product of rms voltage and rms current. The unit for reactive power is var, which stands for volt-ampere reactive.

Test: Basic & Electric Circuits- 1 - Question 8
Save

The unit of electrical energy is

Detailed Solution: Question 8


  • The unit of electrical energy is the Joule (C).

  • Electrical energy is the work done by electrical power over time.

  • One Joule is the energy transferred when one watt of power is applied for one second.

  • Watt (A) is a unit of power, not energy.

  • Kilowatt (B) is 1,000 watts, still a unit of power.

  • Kilowatt-hour (D) is a larger unit of energy used for billing electricity.
