Answer 1

__16. **d. series circuit**In a series circuit, components are connected end-to-end, forming a single path for electron flow.__17. **b. The sum of voltages of the loads in a loop equals the voltage of the energy source.**Kirchhoff's Voltage Law (KVL) is also known as the loop rule. It states that the algebraic sum of the potential differences (voltages) in any closed loop or mesh in a network is always equal to zero. This is essentially a statement of conservation of energy.__18. **c. from right to left**Magnetic field lines emerge from the north pole (N) and enter the south pole (S). Therefore, above and below the magnet, the field lines will point from the N-pole on the right towards the implied S-pole on the left.
