The voltage across a 10-ohm resistor carrying 3 amps must be?
What is thirty volts?
V=IR
Is the answer 30?
To determine the voltage across a resistor, you can use Ohm's Law, which states that the voltage (V) equals the current (I) multiplied by the resistance (R). Therefore, you can calculate the voltage using the formula:
V = I * R
In this case, the current flowing through the resistor is given as 3 amps, and the resistance is 10 ohms. By substituting these values into the formula, you can calculate the voltage:
V = 3 A * 10 Ω
V = 30 volts
Therefore, the voltage across the 10-ohm resistor carrying 3 amps is 30 volts.
