$O P = V _ { 1 } ^ { 2 } + V _ { 2 } ^ { 2 } + 2 \left( V _ { 1 } \right) \left( V _ { 2 } \right) \cos \theta$

Short Answer

$O P = V _ { 1 } ^ { 2 } + V _ { 2 } ^ { 2 } + 2 \left( V _ { 1 } \right) \left( V _ { 2 } \right) \cos \theta$ A transformer secondary circuit is shown. Find $I _ { S }$ . Express the answer to the nearer tenth. Hint: First apply Ohm s law E=IR to find $I _ { H }$ and $I _ { L }$ .
