Example 1
For the circuit in the diagram above,
Answer:
a.
Potential difference across the 2Ω resistor,
V = 12V
Resistance, R =2Ω
V=IR
(12)=I(2)
I=6Ω
b.
The current flows through the resistor
= the reading of the ammeter
= 6Ω
Example 2
For the circuit above,
Answer:
a.
Potential difference across the 2 resistors, V = 12V
The equivalent resistance of the 2 resistors, R =6Ω
V=IR
(12)=I(6)
I=2Ω
b.
The current flows through the resistors
= the reading of the ammeter
= 2Ω
