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…

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.

Six circuits containing a battery and two or more bulbs are shown here. A. In which circuits are A and B connected in series with each other? 1 2 3 4 5 6 B. In which circuits are A and B connected in parallel with each other? 1 2 3 4 5 6 Bulb A has a resistance of 2 Ω; bulb B has a resistance of 6 Ω; bulb C has a resistance of 5 Ω; the battery has a potential difference of 6 V. C. What are the total resistance Rtot and the current flowing from the battery I in circuit 1?Rtot = ΩI = A

The circuit in the figure below contains two resistors, R, 2.20 kN and R, = 3.10 kN, and two capacitors, C, = 2.10 µF and C, = 3.10 µF, connected to a %D battery with emf & = 115 V. There are no charges on the capacitors before switch S is closed. R1 C1 7. R2 C2 3. (i (a) Determine the charge on capacitor C, as a function of time (in ms), after the switch is closed.
