A ` 10 Omega` electric heater operates a 110 V line. The rate at which heat is developed in watts is :

A

1310 W

B

670 W

C

810 W

D

1210 W

Text Solution

Verified by Experts

The correct Answer is:
D
The rate at which heat is developed
` " " H = (V^(2))/(R ) `
` " " = ((110)^(2))/(10)`
` " " = 1210 W`
