Question

(a) What is the current through the battery?
A

(b) What is the current through the resistor?
A

(c) What is the power dissipated in the resistor?
W

(d) How much energy is dissipated in the resistor in 3.5 minutes?
J

A resistor with R = 90 ? is connected to a battery with emf e m f = 5.5 V. (a) What is the current through the battery? A (b) What is the current through the resistor? A (c) What is the power dissipated in the resistor? W (d) How much energy is dissipated in the resistor in 3.5 minutes? J

Explanation / Answer

b)current through the ressitor = 5.5/90 = 0.0611 A (ans)

a)current throguh the battery = 0.0611 A (ans)

c) power dissipated =I2R = 0.06112*90 = 0.3361 W(ans)

d)energy = P*T = 0.3361* 210 = 70.58 J (ans)
