Priyanka B Solutions for Chapter: Electricity, Exercise 7: Practice Problems-IV

What would be reading of ammeter and voltmeter in the given circuit?

(i) Draw a schematic diagram of a circuit consisting of a $24 \mathrm{V}$ battery, a $10 \mathrm{ohm}$ resistor, a $5 \mathrm{ohm}$ resistor, a $1 \mathrm{ohm}$ resistor, an ammeter and a plug key, all connected in series.

(ii) Calculate the ammeter reading in this circuit.

A battery of $9 \mathrm{V}$ is connected in series with resistors of $0.2 \mathrm{\Omega }, 0.3 \mathrm{\Omega }, 0.4 \mathrm{\Omega }, 1.5 \mathrm{\Omega }$ and $12 \mathrm{\Omega }$ resistors. How much current would flow through the $12 \mathrm{\Omega }$ resistor?
