Answer:
4.41 W
Explanation:
P = IV, V = IR
P = V² / R
Given that P = 0.0625 when V = 1.50:
0.0625 = (1.50)² / R
R = 36
So the resistor is 36Ω.
When the voltage is 12.6, the power consumption is:
P = (12.6)² / 36
P = 4.41
So the power consumption is 4.41 W.
Answer:
Part c)
Explanation:
Light bulb is marked as 75 W and 120 Volts
so it means that when we apply 120 volts across the bulb then it will consume the total power of 75 W
now when we connected the bulb with the help of conducting wires with some resistance across them then few of its voltage will fall across the wires
due to which the voltage across bulb is less than 120 Volts
So the power given by the bulb is less than 75 W
Part c)
Resistance of the bulb is given as
now total resistance of the circuit
now current in the circuit
so actual power delivered to the bulb is given as
Answer
Given,
Current, I = 14.6 A
magnetic force per unit length = 0.119 N/m
Magnitude of magnetic field = B = ?
a) F = ILB sin θ
θ = 90°
So,
b) The direction of magnetic field is in +z direction.
The correct option is C.
From the information given above, one can easily conclude that electromagnetic Y is the strongest because, it produces the higher amount of current compare to the other electromagnets. Electromagnet W is the weakest because it produces the lowest amount of current.
