How can I find the potential difference?
It's a parallel circuit. R1, R2 and R3 is 0.3 and the current is 8.0.
Is the volts 8.8?
If that is 0.3 ohm apiece, then total R is 0.1. Then E = IR = 8*0.1 = ? Is that right?
To find the potential difference in a parallel circuit, you need to know the current and the resistance values of the individual resistors. In this case, you have been given the current (8.0 Amps) and the resistance value of each resistor (0.3 Ohms).
In a parallel circuit, the potential difference (or voltage) across each resistor is the same. This means that the voltage across R1, R2, and R3 will all be equal.
To calculate the potential difference, you can use Ohm's Law, which states that V (potential difference) equals I (current) multiplied by R (resistance). Since the resistance values are the same for all resistors, the potential difference across each resistor will also be the same.
So, the potential difference for each resistor is:
V = I * R
V = 8.0 A * 0.3 Ω
V = 2.4 Volts
Therefore, the potential difference across R1, R2, and R3 is 2.4 Volts, not 8.8 Volts.
