The Calculation of Electric Current Through a Resistor

Explanation:

Ohm's Law: Ohm's law states the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The formula is V = I * R, where V is the voltage across the component, I is the current flowing through the component, and R is the resistance of the component.

Given data:

• Potential difference between the yellow wire and black wire (ground) = 4.73 volts
• Voltage across the 330 ohm resistor = 2.53 volts

To find the electric current (I) passing through the resistor, we can use Ohm's Law:

I = V / R

Substitute the given values into the formula:

I = 2.53 volts / 330 ohms

I = 0.00766667 amperes

Since 1 milliamp is equal to 0.001 amps, the current can be converted to milliamps:

0.00766667 amperes * 1000 = 7.66667 milliamps

Therefore, the value of the electric current passing through the 330 ohm resistor is 7.66667 milliamps.
