Current & Voltage Flashcards
1
Q
What is Current?
A
The flow of electrons.
Symbol: I
Unit: Ameter
Unit Symbol: A
2
Q
What is Voltage?
A
The charge of energy.
Symbol: AC
Unit: Volt
Unit Symbol: V
3
Q
How are current and voltage related according to Ohm’s Law?
A
V = I × R, where V is voltage, I is current, and R is resistance.
4
Q
Voltage in simple electrical circuit
A
Voltage represents the electric potential difference that drives current through a resistor, converting electrical energy into other forms, like heat.
5
Q
Resistance
A
An object that stops the electrical current.
Symbol: R
Unit: OHM
Unit Symbol:
6
Q
Concept of path of least resistance
A
Current flows more through paths with lower resistance, avoiding higher resistance paths.
