Three resistors of resistances 5 Ω, 3 Ω and 2 Ω are connected in series with 10 \(V\) battery. Calculate their effective resistance and the current flowing through the circuit.
 
\(R_{1}\) \(=\) 5 Ω
 
\(R_{2}\) \(=\) 3 Ω
 
\(R_{3}\) \(=\) 2 Ω
 
\(V\) \(=\) 10 \(V\)
 
The formula to calculate the effective resistance is
 
RS=ii+ii+ii
 
Effective resistance of the circuit \(=\)  Ω
 
The formula to calculate the current flowing through a series circuit is,
 
I=iii
 
Current flowing through the circuit \(=\)  \(A\)
