Answer:

[tex]I=3A[/tex]

Explanation:

From the question we are told that:

Number of lamps [tex]N=4[/tex]

Potential difference [tex]V=60v[/tex]

Total Resistance of the lamp is [tex]R= 20ohms[/tex]

Generally the equation for Current I is mathematically given by

 [tex]I=\frac{V}{R}[/tex]

 [tex]I=\frac{60}{20}[/tex]

 [tex]I=3A[/tex]
