Heat energy is being produced in a resitance 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 ?

Explanation

Data : P=100 W , I=3 A, R=? , `P=I^(2)R`
`therefore ` Resistance `, R=(P)/(I^(2))=(100W)/((3A)^(2))=(100)/(9) Omega =11.11 Omega`
