A circuit is made of 0.4`Omega` wire, a `150Omega` bulb and a `120Omega` rheostat connected in series. Determine the total resistance of the resistance of the circuit.

Text Solution

Verified by Experts

Resistance of the wire=`0.4Omega`
Resistance of bulb=`150Omega`
Resistance of rheostat=`120Omega`
In series, Total resistance, `R=0.4+150+120=270.4Omega`
