Consider the circuit configurations below, where two lightbulbs are connected to a single battery in different ways. Based on what you learned about parallel and series connections in lab, which of these two configurations would result in the light bulbs being the brightest? Fully explain your reasoning.
Imagine that you are given four 100Ω resistors to build a circuit. Your challenge is to use all four of the resistors in the circuit, but the circuit must have an overall equivalent resistance of 100Ω. Is this possible?
If so, draw a diagram of the circuit and explain how the connections result in a 100Ω equivalent resistance. If this is not possible, draw a diagram of a circuit involving all four resistors that has an equivalent resistance as close to 100Ω as is possible.
I keep getting different answers with each calculation and unsure of where I am going wrong. If possible, please show steps so I may understand where my calculations were incorrect.
(a). What's the capacitance of your capacitor? (the value and unit(s)).
(b). If you disconnect the battery and separate the plates to a distance of 3.50 cm without discharging them, what will be the potential difference between them? (the value and unit(s)).
Consider the circuit diagram depicted in the figure.
Part (a) If the current through the top branch is I2 = 0.025 A, what is the current through the bottom, I3, in amps?
