Question

If an electric bulb 60w is used for 1 hr in month of May. Find the units consumed and cost if 1 unit cost 1.50ps​

Answer 1

Answer:-

• Power=P=60W
• Time=t=24×31=744
• Work done=?

We know

$\boxed{\sf W=Pt}$

$\\ \sf\longmapsto W=60\times 744$

$\\ \sf\longmapsto W=44640wh$

$\\ \sf\longmapsto W=44.6kwh$

Price per kWh=1.50

$\\ \sf\longmapsto Price=44.6\times 1.50$

$\\ \sf\longmapsto Price=66.9units$
