Efficiency = output/input.
= .6\.7.
= .857.
% efficiency = .857*100.
= 85.7%.
= .6\.7.
= .857.
% efficiency = .857*100.
= 85.7%.

Normally the efficiency formula is;
Efficiency =outputpower/inputpower * 100.
Efficiency =outputpower/inputpower * 100.

Efficiency = output/input.
= .6/.7.
= .857.
% = .857 * 100.
= 85.7%.
= .6/.7.
= .857.
% = .857 * 100.
= 85.7%.

Efficiency = (output/input)*100.
Efficiency = (0.6/0.7)*100.
= 85.7%.
Efficiency = (0.6/0.7)*100.
= 85.7%.

Efficiency = output power/ input power = (0.6/0.7)*100 = 85.71%

E = O/I.
= 0.6/0.7.
= 0.857.
E OF 100 % = 0.857*100.
= 85.7%.
= 0.6/0.7.
= 0.857.
E OF 100 % = 0.857*100.
= 85.7%.

Efficacy = Output/input ×100.
0.6/0.7 × 100 = 85.71%.
0.6/0.7 × 100 = 85.71%.

Efficiency = Output/Input.
So, E =.6/.7*100.
= 85.7%.
So, E =.6/.7*100.
= 85.7%.
