Three resistors R R and R, each of 24022 areconnected across a 120 V supply, as shown inFig. 3.139. Find (i) the potential difference acrosseach resistor and (ii) the total heat developed acrossthe three resistorsRin 1 minute.[Ans. O V = 80 V,(i) V2 =V, = 40 V(ii) 2400 ]Fig. 3.139 |

Answer» V1=80V BECAUSE V=RI V= 240÷30= 80 JUST AS V2AND V3ALSO WE CAN FIND |
