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.
gav_18s asking:
How do you work this out?

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
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
