Which row gives the correct description of Kirchhoff’s laws?
- AFirst law: The sum of the currents entering a junction equals the sum of the currents leaving the junction (physics principle: conservation of charge). Second law: The sum of the e.m.f.s around any closed loop in a circuit equals the sum of the p.d.s around the same loop (physics principle: conservation of energy).
- BFirst law: The sum of the currents entering a junction equals the sum of the currents leaving the junction (physics principle: conservation of energy). Second law: The sum of the e.m.f.s around any closed loop in a circuit equals the sum of the p.d.s around the same loop (physics principle: conservation of charge).
- CFirst law: The sum of the e.m.f.s around any closed loop in a circuit equals the sum of the p.d.s around the same loop (physics principle: conservation of energy). Second law: The sum of the currents entering a junction equals the sum of the currents leaving the junction (physics principle: conservation of charge).
- DFirst law: The sum of the e.m.f.s around any closed loop in a circuit equals the sum of the p.d.s around the same loop (physics principle: conservation of charge). Second law: The sum of the currents entering a junction equals the sum of the currents leaving the junction (physics principle: conservation of energy).
