A 4.8 mF capacitor in series with a 500 Ω resistor is connected, by a switch, to a 12 V battery. The current through the resisto r at t = 1.0 s, after the switch is closed is: a. 64 mA b.25 mA
c.49 mA
d.64 mA
2 answers:
Answer:
The current is 15.8 mA.
Explanation:
Given that,
Capacitor = 4.8 mF
Resistor = 500 Ω
Time t = 1.0 s
Voltage = 12 V
We need to calculate the current
Using formula of current
Where, V = voltage
R = resistance
t = times
Put the value into the formula
Hence, The current is 15.8 mA.
Answer:
Current will be 81.7 mA
Which is not given in bellow option
Explanation:
We have given capacitance
Resistance R = 500 ohm
Voltage V = 12 volt
We know that time constant of RC circuit of RC circuit is given by
Time is given as t = 1 sec
We know that current in RC circuit is given by
So current

Because it records speed of the car at a certain time, the independent variable should be time and dependent would be speed or velocity. Since it's taken every second, it would be considered instantaneous velocity, which is D.
Answer:
m = 0.4 [kg]
Explanation:
Weight is considered as a force and this is equal to the product of mass by gravitational acceleration.
where:
W = weight = 0.8 [N]
m = mass [kg]
g = gravity acceleration 2[N/kg]
