A coffee maker is rated at 1200 W, a toaster at 1100 W, and a waffle maker at 1400 W. The three appliances are connected in parallel to a common 120 V household circuit. What is the current in each appliance when operating independently? What total current is delivered to the appliances when all are operating simultaneously? Is a 15A circuit breaker sufficient in this situation? Explain.
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.
