Final answer:
The current flowing in a circuit supplied by a 60-Hz, 120-volt source with a 0.03-henry coil can be found by calculating the inductive reactance and then applying Ohm's law. After calculations, the current is approximately 10.61 amperes.
Step-by-step explanation:
To determine how much current will flow in a circuit that is supplied by a 60-Hz, 120-volt source and has a 0.03-henry coil, we need to calculate the inductive reactance (XL) of the coil and then use Ohm's law to find the current (I). The inductive reactance is given by the formula XL = 2πfL, where f is the frequency in hertz and L is the inductance in henries. Plugging in the values, we get XL = 2π(60)(0.03) = 3.6π ohms. Once we have XL, we can use Ohm's law, which states I = V / XL, where V is the voltage. Therefore, the current I = 120 volts / (3.6π ohms) = 120 / (3.6π) amperes. After performing the calculation, we find that the current flowing in the circuit is approximately 10.61 amperes.
