1.	6. An electric iron of resistance 660 Ohms is connected to a main supply of 220 V. Compute the current through the element and the amount of heat produced in Joules in 11 minutes.
Answer» ONG>Answer: R = 660 V =220 V = IR 220 = I×660 I = 220/660 I = 2/6 = 1/3 A H = (I)2RT H = (1/3)2×660×11 H = 660×11/9 H = 220×11/3 H = 2420/3 joule

6. An electric iron of resistance 660 Ohms is connected to a main supply of 220 V. Compute the current through the element and the amount of heat produced in Joules in 11 minutes.

Answer» ONG>Answer:

R = 660

V =220

V = IR

220 = I×660

I = 220/660

I = 2/6 = 1/3 A

H = (I)2RT

H = (1/3)2×660×11

H = 660×11/9

H = 220×11/3

H = 2420/3 joule
