Question

draw a schematic diagram of a circuit consisting of a battery of three cells of 2V each a 5ohm resistor an 8ohm and a 12ohm resistor and a plug key all connected in series​

Answer 1

It is noted that the ammeter has been put in series with the circuit and the voltmeter has been put in a parallel with12Ω resistor. (i) Calculation of current reading in the ammeter: (ii) Calculation of potential difference reading across 12 Ω resistor. Current,I=0.24A,Resistance,R =12Ω, Potential difference,V =? Applying Ohm's law v = IR= 0. 24 x 12= 2.88 V Therefore, the voltmeter reading is 2.88 V.Read more on Sarthaks.com - https://www.sarthaks.com/23789/draw-schematic-diagram-of-circuit-consisting-of-battery-of-three-cells-of-2v-each-resistor?show=23790#a23790
