Answer:
1.6 s
Explanation:
To find the time in which the potential difference of the inductor reaches 24V you use the following formula:

V_o: initial voltage = 60V
R: resistance = 24-Ω
L: inductance = 42H
V_L: final voltage = 24 V
You first use properties of the logarithms to get time t, next, replace the values of the parameter:

hence, after 1.6s the inductor will have a potential difference of 24V
1 Ampere
Explanation:
1/R = 1/8 + 1/10 + 1/12
1/R = (30 + 24 + 20) / 240
1/R = 74 / 240
R = 240 / 37
R = 120/37 Ohms
We know that,
V = IR
I = V/R
I = 12 / (120/37)
I = 12 × 37/120
I = 37/10
I = 3.7 A
Now,
The current in 12 ohm resistor →
= 1 A
∴ The current in 12 ohm resistor is 1 ampere
Answer:
because all power is being stored in the battery instead of draining the battery getting a result of a smaller and smaller voltage put through the circuit
Explanation:
say the battery is 1.5 volts, in a circuit it is slowly decreasing the power output of 1.5 volts to 0 volts by using the power within the battery when you have the battery disconnected the voltage will remain the same as which you left it
Answer:
The mass of a tennis ball is 59 grams.
Explanation:
Given that the formula for momentum is p = m×v where m represents mass (kg) and v is speed (m/s). Then, you have to substitute the values :
