-- A stack of several cells connected in series presents several times the voltage
of a single cell.
-- The current depends on the 'load' connected between the battery's terminals.
But since the current through any load is directly proportional to the voltage across
it, several cells in series ... with their increased voltage ... will produce several times
as much current as the same load would draw from a single cell.
if resistors connected in series the resistance will increase.Then it limit the flow of current through it. voltage may be increased. A: by connecting any resistors in series it will limit the current flow it will effect the current but never the voltage applied
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
Less current.
You apply a voltage across a load and the result is that a current flows through the load. So you must have the voltage present, the cause, before current flow, the effect. Think of voltage as pressure and current as flow.
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879
That depends on the circuit - but note that in almost all real circuits the current is the dependent variable - you control the voltage and the current sets itself.
By Ohm's Law, current is voltage divided by resistance, so if you double both the voltage and the resistance, the current would remain the same.
There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.
An effect of connecting a poor contact in an electrical circuit could be intermittent current flow.
Hall Effect
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
