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.
Consider a series RC circuit
as in Figure P18.35 for
which R = 1.00 MΩ, C =
5.00 µF, and ε = 30.0 V.
Find (a) the time constant
of the circuit and (b) the
maximum charge on the
capacitor after the switch is
thrown closed. (c) Find the
current in the resistor 10.0 s
after the switch is closed.
