Single loop circuits.

Kirchoff's First Law states

• the sum of the currents entering any junction in an electric circuit must equal the sum of the currents leaving that junction

• the sum of the charges entering any junction in an electric circuit must equal the sum of the charges leaving that junction

• the sum of the emfs entering any junction in an electric circuit must equal the sum of the pds leaving that junction

• none of these

Kirchoff's second law states

• in any closed loop in an electric circuit the algebraic sum of the electromotive forces in the loop is equal to the algebraic sum of the potential differences in that loop

• in any closed loop in an electric circuit the vector sum of the electromotive forces in the loop is equal to the vector sum of the potential differences in that loop

• in any closed loop in an electric circuit the algebraic sum of the currents in the loop is equal to the algebraic sum of the potential differences in that loop

• none of these
