Question

Draw a schematic diagram of an electric circuit consisting of a battery of five 2V cells, a 20 ohm resistor, a 30 ohm resistor, a plug key, all connected in series. Calculate the value of current flowing through the 20 ohm resistor and the power consumed by the 30 ohm resistor.

Answer 1

I = V/R
  =10V/20ohm
  =.5A(ampere)


P = V× I
   = 10×.5
   = 5W(wartz)

Answer 2

Answer:

Hope it helps

I = 0.5 Ampere
