Heat energy is being produced in a resistance in a circuit at the rate of 100 W. The current of 3 A is flowing in the circuit. What must be the value of the resistance ?

Answer

The value of resistance in the circuit is `11 Omega`

Explanation

`"Given: Power (P) = 100 W, Current (I) = 3 A"`
`"To find: Resistance (R)"`
`"Formulae: i. P VI ii. V = IR"`
`"Calculation: From formula (i),"`
`V=(P)/(I)=(100)/(3)=33.3V`
From formula (ii),
`R=(V)/(I)=(33.3)/(3)~~11Omega`
