a 13 ohm resister has 0.050 A of current in it. What is the potential difference across the resistor?
To find the potential difference across a resistor, you can use Ohm's Law, which states that V (potential difference) across a resistor is equal to the product of the current (I) flowing through it and its resistance (R).
The formula for Ohm's Law is:
V = I * R
Given:
Resistance (R) = 13 ohms
Current (I) = 0.050 A
Now, let's substitute these values into the formula to find the potential difference (V):
V = 0.050 A * 13 ohms
V = 0.65 volts
Therefore, the potential difference across the resistor is 0.65 volts.
To find the potential difference (or voltage) across a resistor, you can use Ohm's Law equation: V = I * R, where V is the potential difference, I is the current flowing through the resistor, and R is the resistance.
In this case, you are given the resistance R as 13 ohms and the current I as 0.050 A. Plugging these values into the Ohm's Law equation, we get:
V = 0.050 A * 13 ohms
Now, we can calculate the potential difference:
V = 0.65 volts
Therefore, the potential difference across the resistor is 0.65 volts.
