Module 3. Electrical fundamentals

A 48-volt direct current source is required to furnish 192 watts to a parallel circuit consisting of three resistors of equal value. What is the value of each resistor?

  • 12 ohm.
  • 36 ohm.
  • 4 ohm.

give Voltage=48v, Power=192W

so total Current.= power÷voltage
= 192÷48
= 4 A
total resistance = Voltage÷Current
= 48÷4
= 12 ohms
circuit have 3 equal parallel resistor
then each resistor have value = 12×3
= 36 ohms
