ohm's law ..... E = I x R
but the facts are that most of the time the voltage (E) is fixed so I = E / R
so the higher the resistance, the lower the current. http://en.wikipedia.org/wiki/Electrical_resistance A resistance resist the current to flow and makes the current lower in an electrical circuit. The voltage in an electrical circuit is given from the source (battery etc) and will not be higer by adding a resistance, but in the part of the electrical circuit where you put the resistance the voltage could be higer (and it would then be lower other parts)
What else can I help you with?
What does power divided by speed equal?
Ohm so correctly said: Voltage divided by current equals resistance. Voltage divided by current will tell you the value of a circuit's resistance. But resistance is not affected by either voltage or current. It is determined by the length, cross-sectional area, and resistivity (type of conducting material) of the conductor. Resistivity is, in turn, affected by temperature. So voltage divided by current tells you what the resistance happens to be - changes in voltage or current do not affect resistance.
What gets used up in an electric circuit current or energy?
One of Kierchieff's laws tell us that the more wattage (energy) consumed by an electrical device in a circuit, the larger the voltage difference that exists across the device and the greater the current flowing through it. The energy consumed is directly proportional to the Impedance of the electrical device but is more importantly proportional to the square of the current. WATTS=VOLTS X AMPERES= RESISTANCE (IMPEDANCE) X AMPERES X AMPERES A Circuit with Current but without resistance would exhibit no energy at all.
What is the effect on current through a circuit of steady resistance when the voltage is doubled?
The current will increase and will flow more. If voltage increases, current must increase.
One way to make current is to use a what?
You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R
Does a large current in a circuit make a bulb bright or dim?
The glow of the bulb is due to heating of the filament to the incandescent level. Joule's heating effect gives the formula H = I2 R t. Hence more the current then more the heat and so more brightness. Thus large current makes the bulb brighter no doubt. At the same time if current exceeds the nominal level then filament would get melted and get fused.
How are current, voltage, and resistance related in an electrical circuit?
In an electrical circuit, current is directly proportional to voltage and inversely proportional to resistance. This relationship is described by Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R), or I V/R.
What is the formula for calculating the resistance in an electrical circuit?
The formula for calculating resistance in an electrical circuit is R V/I, where R is the resistance, V is the voltage, and I is the current.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship between current, voltage, and resistance in an electrical circuit?
In an electrical circuit, current is the flow of electric charge, voltage is the force that drives the current, and resistance is the opposition to the flow of current. According to Ohm's Law, the relationship between current (I), voltage (V), and resistance (R) is given by the equation V I R, where voltage equals current multiplied by resistance.
What is the relationship between voltage, current, and resistance in an electrical circuit?
In an electrical circuit, voltage is the force that pushes electric current through a conductor. Current is the flow of electric charge, and resistance is the opposition to the flow of current. According to Ohm's Law, the relationship between voltage (V), current (I), and resistance (R) is given by the equation V I R. This means that the voltage across a circuit is equal to the current flowing through it multiplied by the resistance of the circuit.
What causes a voltage drop in an electrical circuit?
A voltage drop in an electrical circuit is caused by resistance in the circuit components, such as wires, resistors, or other devices. This resistance reduces the flow of current and results in a decrease in voltage across the circuit.
What is the relationship between resistance and voltage in an electrical circuit?
In an electrical circuit, resistance and voltage are directly related. According to Ohm's Law, voltage is equal to the product of resistance and current. This means that as resistance increases, voltage also increases, and vice versa.
What is the relationship between voltage and resistance in an electrical circuit?
In an electrical circuit, the relationship between voltage and resistance is described by Ohm's Law. This law states that the voltage across a circuit is directly proportional to the resistance in the circuit. In other words, as resistance increases, the voltage required to maintain the same current also increases. Conversely, if resistance decreases, the voltage required to maintain the same current decreases.
What is the relationship between current and voltage in an electrical circuit?
The relationship between current and voltage in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the circuit. In simpler terms, as the voltage increases, the current flowing through the circuit also increases, assuming the resistance remains constant.
What is the relationship between voltage and current in an electrical circuit?
The relationship between voltage and current in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the circuit. This means that as the voltage increases, the current flowing through the circuit also increases, assuming the resistance remains constant.
How does voltage drop work in an electrical circuit?
Voltage drop in an electrical circuit occurs when there is resistance in the circuit, causing a decrease in voltage as the current flows through the components. This drop in voltage is proportional to the amount of resistance in the circuit, following Ohm's Law (V I R).
How do you figure out how much current is in an electrical wire?
If you know the voltage and resistance, then current = voltage divided by resistance. Otherwise, you can attach an ammeter into the circuit (in series).
