I have a resistor of 230 [Ohm] and apply a voltage across it of 9 [Volt]. What is the current through the resistor in milliAmp?
[mA]
I = V/R = 9/230 = 0.0391 Amps = 39.1 mA.
To calculate the current through a resistor, you can use Ohm's Law, which states that the current (I) flowing through a resistor is equal to the voltage (V) across the resistor divided by its resistance (R).
Ohm's Law formula: I = V / R
Given:
Voltage (V) = 9 [Volt]
Resistance (R) = 230 [Ohm]
Substituting these values into the formula, we get:
I = 9 [Volt] / 230 [Ohm]
Now, let's calculate the current:
I ≈ 0.0391 [Amp]
To convert Amps to milliamps (mA), we multiply the value by 1000:
I (in mA) = 0.0391 [Amp] × 1000
I (in mA) ≈ 39.1 [mA]
Therefore, the current flowing through the resistor is approximately 39.1 mA.
