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.
- What is the resistance of a light bulb if 0.50 A flows through it when 120 V is connected across it?
2. What is the resistance of a 5.4-m length of copper wire 1.5 mm in diameter? r = 1.68 x10-8 W×m
3. What is the maximum power consumption of a 3.0-V portable CD player that draws a maximum of 240mA of current?
