Question

a circuit consist of two parallel resistor having resistance of 20 ohm and 30 ohm respectively connected with series of 15 ohm.if current through 15 ohm is 3A what is the power​

Answer 1

Answer:

81

Explanation:

according to your question this circuit should be like this

so we need to identify total resistances R= (1/20+1/30)^-1+15 = 27 ohm

So power should be V= 27 *3 = 81
