Science: Chapter 13: Electrical Systems
V=I x R
V is voltage of battery, I is amount of current and R is the total effective resistance
Used to calculate voltage, resistance and current
Total resistance in series circuit
R1+ R2(Total resistance in all appliances)
(R1+R2)^-1 (R1 and R2 are parallel to each other)
voltage is treated as constant in the series circuit
Current will split in the case of parallel
more current passes through resistor of less resistance
parts of a electrical system
ammeter
connected in series to measure electric current(amphereA)
Voltmeter
connected in parallel to measure voltage(Volts(V)
resistors
fixed resistor
Variable resistor(rheostat)
benefits of electrical systems
coating of electrical systems
medical instruments andimplantd
harmful effects of electrical system
electrical fire
electric shock
safety devices in household
fuse
melts when current is too high, stop current from flowing
circuit breaker
it trips when there is fault appliance
