Q
what is the electrical current rule
A
the algebraic sum of the currents entering a junction is equal to zero (the sum of all the currents entering at one point is equal to the sum of all the currents leaving that point
2

A
around a closed-loop (not necessarily) a full circle the sum of the emf is equal to the sum of the pd around the loop
