Vedclass · Answer

(A) Parallel wires carrying current in the same direction attract each other,while those carrying current in opposite directions repel each other.Let the current in wires $P, Q,$ and $R$ be $I_P = 2A, I_Q = 4A,$ and $I_R = 6A$ respectively. All currents are in the same upward direction.Force on wire $R$ due to wire $P$ $(F_{RP})$: Since currents are in the same direction,$P$ attracts $R$. The force $F_{RP}$ is directed towards the left (towards $P$).Force on wire $R$ due to wire $Q$ $(F_{RQ})$: Since currents are in the same direction,$Q$ attracts $R$. The force $F_{RQ}$ is directed towards the left (towards $Q$).Since both forces $F_{RP}$ and $F_{RQ}$ act towards the left,the resultant force on wire $R$ is towards the left.

$P, Q$ and $R$ are long parallel straight wires in air,carrying currents as shown in the figure. The direction of the resultant force on wire $R$ is
