Lower than what? For the same voltage, a lower resistance means higher current. But beware, the voltage itself might depend on the current - thus - with a fixed resistance if you change the voltage, you will increase the current in the same proportion. Some things become higher resistance if they get hot (a tungsten filament in a lamp). Other things become lower resistance if they get hot (semiconductors). So it can all depend on what kind of circuit you have.

What is the importance of the reverse-to-forward resistance ratio of a diode?
to determine the comparison of resistance value of both forward and reverse diode . The more the resistance the lower the current , the lower the resistance the higher the current . When reverse bias , the resistance is high and it acts in open circuit and the reverse current is very small that can be neglected . When forward bias , the resistance is low and it acts as short circuit and the forward current is increasing as the voltage supply is higher .
How a slip ring motor work?
The stator coil is exactly the same as a 3 phase induction motor. The difference being the rotar which has 3 phase wiring in star point or delta connection and also has the sliprings connected to the wiring of the rotor. Brushes are use for the contact between the surpply and the rotor. By controling the current we can control the torgue and speed of the motor. This is done with resistance. Resistance can be greated by means of a resistance bank, liquid resistance or a variable resistance. The basic Idee is: The higher the resistance, low starting current, high torque, high % slip. Motor runs slowlyLow resistance , Higher starting current, lower torgue, lower % slip Motor runs faster.Thus by varing the rotor resistance the motor can be adapted for a spesific load.The motor Are mainly used for Overhead cranes, Elevators in buldings, Pumps under pressure and large fans
If voltage remains constant and resistance decreases current flow?
the current will increase because of a lower level of resistance , hence more current will flow- easily
A dangerous circuit with low resistance and high current?
Another name for a circuit with low resistance and high current is a short circuit. It is dangerous because, if you have sufficient energy in the power source, you can damage components and/or cause fires.
Why might the current in a short circuit be higher than the current in the original circuit?
The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.
HOw does electricity get transported and why does it need to be at a high voltage?
The primary reason that power is transmitted at high voltages is to increase efficiency. ... The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.
If one branch of a parallel circuit has high resistance?
If one branch of a parallel circuit has high resistance, it will draw less current compared to branches with lower resistance. This means that most of the total current will flow through the lower-resistance branches. Consequently, the voltage across all branches remains the same, but the overall current provided by the power source will be affected, potentially resulting in decreased total current in the circuit.

Do conductors or insulators have a lower resistance?
Conductors have lower resistance compared to insulators. Conductors allow electric current to flow easily due to the presence of free electrons that can move through the material, while insulators have high resistance as they do not allow the flow of electric current easily.
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
Corrosion in a circuit results in high current flow?
When there is corrosion in a circuit, it results in lower current flow. This is because corrosion actually causes resistance.
Is the input resitance of an ideal ammeter is low and the output resistance is high?
An ammeter does not have an 'output resistance'. It's important that its resistance is low so as not to add additional resistance into the circuit to which it is connected, otherwise the 'measured current' would be lower than the actual current.
How does a rheostat make a current high?
A rheostat is a variable resistor that can increase or decrease the resistance in a circuit. By increasing the resistance in the circuit, the rheostat limits the flow of current, causing it to become higher in the parts of the circuit where the resistance is lower.
When is the current flowing in a circuit said to be very small?
The current flowing in a circuit is said to be very small when it is in the range of microamperes (10^-6 A) or even lower. This low current can be indicative of high resistance or very low power consumption in the circuit.
How do you lower the current?
To lower the current in a circuit, you can increase the resistance using Ohm's Law (I = V/R), where I is the current, V is the voltage, and R is the resistance. Alternatively, you can reduce the voltage supplied to the circuit, which will also decrease the current. Additionally, adding resistors in series will increase the total resistance and thus lower the current flowing through the circuit.
What does high resistance mean?
High resistance refers to a material's ability to resist the flow of electric current. In electrical terms, it means that the material impedes the movement of electrons, resulting in lower current flow for a given voltage according to Ohm's Law (V = IR). High resistance is commonly found in insulating materials, which prevent electrical conduction and help protect circuits from unwanted current leakage.
What are the purposes of connecting condensers to tweeters?
Speaker is a cupper coil that vibrates and thus making sound. Music is a AC current that flows thru this coil. At low frequencis the resistance of a coil is low and this low resistance means high current that may damage speaker coil. The cendenser cut this low frequencis so only the high frequencis can drive the tweeter and make it safe. Overall at AC current lower the frequency lower the coil resistance and higher the condenser resistance. Higher the frequency higher the coil resistence and lower the condenser resistence.
