Q: A coil of wire is placed in a changing magnetic field. What happens to the induced current if the resistance of the coil is increased?

Solution: According to Ohm's law, if the resistance increases while the induced EMF remains constant, the induced current will decrease.

Steps: 5

Step 1: Understand that a coil of wire in a changing magnetic field creates an induced current.
Step 2: Know that the induced current is related to the induced EMF (electromotive force) in the coil.
Step 3: Remember Ohm's law, which states that current (I) equals voltage (V) divided by resistance (R): I = V / R.
Step 4: If the resistance (R) of the coil increases and the induced EMF (V) stays the same, the current (I) will decrease.
Step 5: Conclude that increasing the resistance of the coil results in a lower induced current.
