The current in the circuit is 1.14A
I did 240V divided by the total resistance 210 = 1.14
To find E3 I did 1.14 amps x 100 ohms ( R3) and its 114.29 V... (view)
Fri 28 Aug, 2020 07:12 am - Here’s the question:
Three resistors ( 30 ohms, 80 ohms, 100 ohms) each have a voltage rating of 100 VDC. If these resistors are connected in series, can they be connected to a 240 VDC... (view)
