PLEASE ANSWER CORRECTLY. WILL RATE YOU VERY HIGH
Explanation / Answer
820 ohm and 680 ohm are in parallel.So, resultant resistance R = (820 x680)/(820 + 680)
R = 371.733 ohm
R and 960 ohm are in series.
So equivalent resisstance of the circuit R ' = R + 960
= 1331.73 ohm
Potential difference V = 12 V
Current through the circuit i = V/R '
= 12 /1331.73
= 9.01 x10 -3 A
Voltage across 960 ohm is V ' = i (960)
= 8.65 volt
Voltage across R is V " = i R
= (9.01 x10 -3 ) (371.73)
= 3.35 volt
(B). the voltage across 820 resistor = 3.35 volt
(C).the voltage across 960 resistor = 8.65 volt
(D).the voltage across 680 resistor = 3.35 volt
