If a coil with a resistance of 10 ohms has an induced EMF of 20 volts, what is the induced current?
Step 1: Identify the values given in the problem. We have a resistance (R) of 10 ohms and an induced EMF (V) of 20 volts.
Step 2: Recall Ohm's law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula is I = V / R.
Step 3: Substitute the values into the formula. Replace V with 20 volts and R with 10 ohms: I = 20V / 10Ω.
Step 4: Perform the division. Calculate 20 divided by 10, which equals 2.
Step 5: State the result. The induced current (I) is 2 amperes (A).
Ohm's Law – Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.
