This is measured in Ohms (Ω).
What is resistance?
What is the circuit symbol for a resistor?
A material in which electrons cannot travel through easily.
What is an insulator?
Calculate current (I). Voltage= 10V, Resistance= 20Ω. Remember to include the correct units!
What is 0.5 Amperes?
Why is a short circuit dangerous?
The current increases and flows back into the circuit, potentially causing fires.
Circuit diagram symbol for a 2 cell battery
Electrons flow freely through metals such as copper, gold, sliver, and aluminum.
What is a conductor?
Find the current through a 12-ohm resistive circuit when 24 volts is applied.
What is 2 Amps?
A series circuit with 2 lightbulbs and an open switch.
THIS component is used to supply energy to an electric circuit by converting chemical energy into electric potential energy.
What is a battery/electrochemical cell?
Describe the trend for current and voltage in a series circuit.
Current: same throughout the entire series circuit.
Voltage: Each load loses a portion of the total voltage of the battery// Voltage lost on each load adds up to the total voltage of the battery.
Electrochemical cell, batteries, or electrical outlet are all...
What is a Source?
You can increase the current in a circuit by doing this.
What is increasing voltage?
A person may acquire a build up of this type of electricity using friction, conduction or induction.
What is build up of static electricity?
What is the trend for current and resistance in a parallel circuit?
Current: splits between multiple pathways in a parallel circuit// The current through each pathway of the circuit adds up to the total current supplied by the source.
Resistance: total resistance in a parallel circuit is less than the individual resistances. Total resistance is decreased.
Name 3 sources of electrical energy.
What is solar energy, chemical energy, geothermal energy, nuclear energy?
A microwave operates on 1200 W of power and is used for 7 minutes. How much electrical energy is used by the microwave?
504,000 Joules
