What is the resistance in a circuit with a current of 4.0A and a voltage of 2.5 ohms?
R = E/I = 2.5/4 = ___
voltage is volts, not ohms.
Hey oobleck, how do you have a character/avatar?
To find the resistance in a circuit, you can use Ohm's Law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R), expressed as I = V/R.
In this case, you already have the current (I = 4.0A) and the voltage (V = 2.5 ohms). Now, you need to rearrange the equation to solve for resistance (R).
R = V/I
Plugging in the values:
R = 2.5 ohms / 4.0A
Calculating this division:
R = 0.625 ohms
Therefore, the resistance in the circuit is 0.625 ohms.
