Consider the circuit shown below. The current through the ammeter is 2 A. d) Find V1. e) If point P of the circuit is grounded (that is VP = 0V), what is the the voltage at point Q? f) What is the power dissipated by resistor R7?
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 the circuit shown below. The current through the ammeter is 2 A.
d) Find V1.
e) If point P of the circuit is grounded (that is VP = 0V), what is the
the voltage at point Q?
f) What is the power dissipated by resistor R7?
