Voltage (v) = current (i) × resistance (r)
i = v/r = 120/4 = 30 amps
B a third class lever cannot magnify out force!
Answer:
240 V
Explanation:
number of turns in primary coil, Np = 10
Number of loops in secondary coil, Ns = 20
Voltage in primary coil, Vp = 120 V
Let the voltage in secondary coil is Vs.
So, Vs / Vp = Ns / Np
Vs / 120 = 20 / 10
Vs / 120 = 2
Vs = 240 V
Thus, the voltage in secondary coil is 240 Volt.
Answer:
for every action, there is an equal and opposite reaction.
Explanation:
the statement means that every interaction there is a pair of forces acting on the two interacting objects.
