Just as the name of the component implies, electrical current gets resisted and therefore it diminishes unless an equally, larger voltage difference in that section of the circuit is applied.
V=IR
Current is inversely proportional to Resistance (when one goes UP, the other goes DOWN)
Voltage is directly proportional to Resistance

How does clipping circuits work in lab?
A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity. In the forward direction, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.
How are loads connected in a series circuit?
In a series circuit, loads are connected one after the other in a single path. The current flowing through each load is the same, and the voltage is divided among the loads. If one load fails or is disconnected, all the other loads in the circuit will also turn off because the circuit is broken.
Why does voltage in water go down when salt is added?
Sodium chloride is an electrolyte.
Why modern homes use electricity arranged in a parallel circuit?
In a parallel circuit the voltage is the same throughout and current flow is the total that each device (or load) draws. This is so everthing can be designed to run on one fixed voltage such as 115VAC for most small appliances and electronics. The voltage comes in to your house as 230 VAC between two wires (plus an earth ground) for dryers, ovens and other large energy hogs. 115 VAC is then available from either of these two hot wires relative to earth ground. If series circuits were used the voltage would vary from 115VAC available for a single load to something less as each extra load is added so in effect nothing would then work if they orinally were designed for 115VAC.
What would happen to the membrane potential if a substance that makes the membrane permeable to ions is added to the cell?
If a subsance is applied to a cell that makes the membrane more permeable to ions, the interior voltage changes. If the interior voltage becomes more positive (say from Ð70 mV to Ð60 mV), this is called a depolarization. If the interior voltage becomes more negative (say from Ð70 mV to Ð80 mV) it's called a hyperpolarization.
What is Voltage rise?
Voltage Rise : The energy added to a circuit. Voltage drop: The energy removed from the circuit.
What happens in a parallel circuit when one battery is added?
When a battery is added to a parallel circuit, the total voltage in the circuit increases as the new battery adds its voltage to the existing voltage sources. The total current in the circuit may also increase as the additional voltage motivates the charges to flow through the parallel branches of the circuit.
What would happen to the voltage drop across each lamp if you kept adding lamps to a series circuit?
The voltage drop across each lamp would decrease as you add more lamps to a series circuit. This is because the total voltage in the circuit is divided evenly among the lamps, so each lamp receives less voltage as more are added.
What happens to the voltage across the voltage source as more light bulbs are added in a series circuit?
Nothing.
How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
If the resistance in the circuit is increased what will happen to the current and voltage?
* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.
What is added to a circuit to make the current smaller?
The reduction of voltage or the increase of resistance will reduce the current in a circuit.
How do you add a fixture to an electrical circuit?
Any devices that are added to a circuit and need the full line voltage to operate, are added in parallel to any other load devices or fixtures in the circuit.
What happens to the voltage if batteries if they are setup in a parallel and a series circuit?
Assuming all of the individual batteries are the same voltage, if arranged in a parallel circuit the voltage is the same as any one battery. If arranged in a series circuit the voltage will be the sum (the total) of all of the batteries added together.
What would happen if more capacitors were added to a series circuit already containing two capacitors?
A: For one thing the total capacitance will decrease . If the voltage rating are different then more problem will become evident. That is if they are added in series.
What would happen if another bulb was added to another series circuit?
In a series circuit, if another bulb is added, it is going to dim.
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
