Answer:
A capacitor with capacitance C is initially charged with charge q. At time t=0, a switch is thrown to close the circuit connecting the capacitor in series with a resistor of resistance R. (see image below)
What is the current I0 that flows through the resistor immediately after the switch is thrown? Express your answer in terms of any or all of the quantities q, R, and C.
Explanation:
charge on the capacitor,
q = CV
C is the capacitance of the capacitor
V is the voltage across the capacitor
Determine the current flowing through the resistor after the switch is thrown
According to Ohm’s law, current flowing through the resistor is ,
V is the voltage across the resistor
R is the resistance of the resistor
since
Current through the resistor immediately after the switch is thrown
The idea that objects only change their velocity due to a force is encapsulated in Newton's first law. Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
Explanation:
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s)
which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.
Higher wattage means that the bulb will draw more current to it.
100W is more than 75W, so the answer is 2) 100W.
The US is the answer I think
