The circuit diagram below shows two emf sources and a bulb connected in parallel. Also connected in the circuit is a resistor with resistance R = 0.2 Ω . The resistance of the bulb is Rb = 0.5 Ω , and each of the sources has internal resistance: r1 = 0.025 Ω and r2 = 0.02 Ω . If E1 = 13.0 V and E2= 5.0 V , calculate the current I2 flowing in emf source E2.
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.
