An electric heater is rated at 1360 W, a toaster is rated at 960 W, and an electric grill is rated at 1750 W. The three appliances are connected in parallel across a 120 V emf source. (a) Find the current in each appliance. heater A toaster A grill A (b) Is a 32.0 A circuit breaker sufficient in this situation? What is the total possible current through the circuit? , ___ because the total current is A
A 1500 W electric heater is plugged into the outlet of a 120 V circuit that has a 20 A circuit breaker. You plug an electric hair dryer into the same outlet. The hair dryer has power settings of 600 W, 900 W , 1200 W, and 1500 W. You start with the hair dryer on the 600 W setting and increase the power setting until the circuit breaker trips. Under what setting does the circuit breaker trip. Please, no...
An electric heater is rated at 1500 W, a toaster at 750 W, and an electric grill at 1000 W. The three appliances are connected in parallel to common 120 V household circuit. (a) How much current does each draw? (b) Is a circuit with a 25.0 Amp circuit breaker sufficient in this situation? Numerically justify your answer.
1a.All household circuits are wired in parallel. A 1200-W toaster, a 340-W blender, and a 60-W lamp are plugged into the same outlet. (The three devices are in parallel when plugged into the same outlet.) Assume that this is the standard household 120-V circuit with a 15-A fuse. What is the current drawn by the toaster? 1b. What is the current drawn by the blender in the previous problem? 1c. What is the current drawn by the lamp in the...
