A 7.7 V power supply is connected to a 79 Ohm resistor and a 87 Ohm resistor in parallel. What is the total current through the circuit? Round your answer to 2 decimal places.

Respuesta :

The total current through the circuit is 0. 19A

How to determine the current

We have the formula for power to be;

Current, I = V/R

Voltage = 7. 7V

Resistance in parallel = R1R2/ R1 + r2

Resistance in parallel = [tex]\frac{79 * 87}{87 + 79}[/tex] = [tex]\frac{6873}{166}[/tex] = 41. 40 Ohms

Current = [tex]\frac{7. 7}{41. 40}[/tex] = 0. 19 A

Thus, the total current through the circuit is 0. 19A
