Acircuit is made of 0.4 ohm wire, 150 ohm bulb and a 120ohm rheo stat connected inseries. determine the total resistance of the resistance of the circuit?

Total resistance of the circuit is 270.4 ohm

Explanation:
We are given that:
resistance of wire = 0.4 ohm
resistance of bulb = 150 ohm
resistance of rheostat = 120 ohm

We are also given that these components are connected in series. This means that the total resistance is summation of all the series components.

Therefore
Total resistance = 0.4 + 150 + 120 = 270.4 ohm

Hope this helps :)
