[Note: Enter the answer up to two decimal places.]
 
\(R_{1}\) \(=\) 20 Ω
 
\(R_{2}\) \(=\) 4 Ω
 
\(V\) \(=\) 6 \(V\)
 
The formula to calculate total resistance is
 
RS=ii+ii
 
Total resistance of the circuit \(=\)  Ω
 
The formula to calculate the current flowing through a series circuit is
 
I=iii
 
Current flowing through the circuit \(=\)  \(A\)
 
Potential difference across the electric lamp \(=\) \(V\)
 
Potential difference across the conductor \(=\) \(V\)
