Potential difference (aka volatge) is shared between componenets. - This means that if a battery is 10v and one component is 4v, then the other is 6v.
Current is the same - everywhere! -This means that if there is 10A at one point, at another point it will also be 10A.
Resistance adds up- The totals resistance is the sum of all other resistnace in the circuit. -This means that if one component is 10 Ohms…
