IPC Notes Electric Current & Electricity Calculations
Electric Current electric current – the flow of electrons through a conductor resistance – the tendency of an object to resist the flow of electrons
Closed vs. Open Circuits closed circuit – allows the flow of electricity; the circuit is complete
Closed vs. Open Circuits open circuit – prevents the flow of electricity; the circuit is incomplete
Batteries battery – uses voltage differences to create a flow of current
2 Types of Batteries dry cell battery – uses a chemical paste surrounding a carbon rod ex) AA battery
2 Types of Batteries wet cell battery – uses 2 types of metallic plates suspended in a conducting solution ex) car battery
Electricity Calculations V=Ix. R V = voltage (volts) I = current (amps) R = resistance (Ohms)
Electricity Calculations P=Ix. V P = power (watts) I = current (amps) V = voltage (volts)
Electricity Calculations E=Pxt E = energy (kilowatt hours) P = power (kilowatts) t = time (hours)
Practice Problem #1 How much power is used by a light bulb if it uses a current of 1. 2 amps and a voltage of 120 volts?
Practice Problem #2 What is the resistance of an appliance that uses 0. 89 amps when the voltage is 120 volts?
Practice Problem #3 How much current is flowing through a wire with a 4. 5 ohm resistor and a 6 volt battery?
Practice Problem #4 How much power is used if 350, 000 kilowatt hours of energy are used in 58 hours?
Practice Problem #5 What is the voltage of a battery if 4. 5 watts are used with 0. 5 amps of current?
Practice Problem #6 How long does it take a 2 kilowatt appliance to use 36. 5 kwh of energy?
