A. Notice that the switches (indicated by positions A and B) are set to position A, and the capacitors and two identical light bulbs (labeled LB1 and LB2) are not connected. Calculate the equivalent resistance of the circuit and the total current. B. How much current flows through the 5 Ω resistor? How about the 3 Ω resistor? C. How much power is dissipated by each of the resistors?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
A. Notice that the switches (indicated by positions A and B) are set to position A, and the capacitors and two identical light
bulbs (labeled LB1 and LB2) are not connected. Calculate the equivalent resistance of the circuit and the total current.
B. How much current flows through the 5 Ω resistor? How about the 3 Ω resistor?
C. How much power is dissipated by each of the resistors?
D. Now suppose the switches are both changed to position B, such that the capacitors and the identical light bulbs are connected. Which light bulb will turn off first? Explain.
Hint: consider that the resistances of LB1 and LB2 are identical.
E. How much charge will each of the capacitors have in the end?
