used in many electronic products such as mobile phones, laptops, smartwatches, and other devices that are operated by batteries
Current only flows in one direction and applied voltage is quite low
- different from A.C (alternating current) circuits. AC Currents → current changes direction 50 or 60 times every second

Important
more current flows into the branch with less resistance
Important
current splits inversely to resistance. more current flows into branch with lower resistance compared to other
Important
ratio of voltages is equal to ratio of resistance
Important
Direction of current flow depends on potential. flows from high to low. doesnt mean it cant flow back.
to calculate potential at a point, calculate difference between V entering a point then subtract P.D
