Question 2.
Define current.
Show hintHide hint
What moves in an electric circuit?
3Question 3.
What is the unit of measure for resistance?
- Volts
- Amperes
- Ohms
Show hintHide hint
Think of what 'limits' the current.
4Question 4.
Ohm's law states that V = I × R. What does 'R' stand for?
- Voltage
- Resistance
- Current
Show hintHide hint
It’s what 'resists' the flow of current.
Question 5.
Design a basic circuit using an LED, resistors, and a battery. Calculate the appropriate resistance needed to prevent the LED from burning out when powered by a 9V battery.
Show hintHide hint
Focus on the voltage drop across the LED.
Question 6.
A circuit has a current of 3A flowing through a resistor of 6 ohms. Calculate the voltage across the resistor and verify if this is a safe range for common components.
