Answer:
Explanation:
Energy stored in a capacitor = 1/2 C V² where , C is capacitance and V is potential of capacitor.
Putting the values
.5 x C x 12² = .0163
C = 226.4 x 10⁻⁶ F .
Frequency of L-C circuit =
where L is inductance of inductor and C is capacitance of capacitor.
putting the values
3585 =
506.87 x 10⁶ =
= 8.7 x 10⁻⁶ H.
Answer:
Explanation:
The net force exerted on the mass is the sum of tension force and the external force of gravity.
is the tension force.
is the force of gravity.
where is the rope's radius from the fixed point.
From the net force equation above:
Hence the tension force is 6.046N
Answer:
Here the circuit in which a 4Ω resistor resistor is connected in series and two 8Ω resistor resistors are connected in parallel. Also, ammeter and voltmeter connected in series and parallel circuit respectively.
Now,
The maximum power of each resistance is 16 W
The 4Ω resistor is linked in series with the circuit.
so, P o w e r = I
two
R, here i is the current through the resistor resistor R
1 6 = I
two
∗ 4 Ω
i = 2A
Now 2A passes through parallel resistors of 8Ω resistance.
we know that, in parallel, the potential difference must be constant,
the current is divided into two parts, because the same resistance current in each resistance will be half. then the current through each resistor in parallel is
2 A
two
.
= 1 A
So finally the current through the 4Ω resistor = 2 A
current through each 8Ω resistor = 1 A
