As little as possible, since the ammeter must be inserted in the circuit,
and the current it measures must flow through it.

Why transistor is called transfer of resistor?
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
When its bright does an LDR have a high or low resistance?
When it is bright, a Light Dependent Resistor (LDR) has low resistance. LDRs are designed to decrease their resistance in response to increased light levels, allowing more current to flow through them. Conversely, in low light conditions, their resistance increases. Thus, the resistance of an LDR is inversely proportional to the intensity of light it receives.
What is the function of foil resistor?
A foil resistor is a type of precision resistor made from a thin layer of metallic foil. Its primary function is to provide accurate and stable resistance in electronic circuits, often with low temperature coefficients and minimal noise. Foil resistors are commonly used in applications requiring high precision, such as in measurement instruments and audio equipment, due to their excellent stability and low inherent inductance.
How does an ammeter work?
An ammeter is a low voltage voltmeter in parallel with a small resistance resistor. Current flow through the resistor creates a voltage drop across it which is then measured by the voltmeter.
Is it desirable for a battery to have a high internal resistance?
No, it is desirable for a battery to have a low internal resistance.
What wire connection better high or low resistance?
Usually low resistance is better.

What is the Q factor in RLC circuit?
It is related to damping in the circuit using a resistor. Q is inversely proportional to the resistor(R). So if the value of resistance is high, there is a greater damping and the value of Q will be low. if resistance is low, there is small damping and Q will be high. when Q is high(low damping) the graph of voltage across resistor against frequency will be sharp at resonance and the bandwidth will be small when Q is low(high damping) thee graph will be less sharp as the bandwidth will be large. Go do some research on the graphs and the formula of Q factor to understand it better.
What resistance of a connecting wire is less than the resistance of a resistor?
The resistance of a connecting wire that is less than the resistance of a resistor would depend on the materials and dimensions of the wire and resistor. Generally, most connecting wires have very low resistance compared to resistors. Copper wires, for example, have low resistance and are commonly used for connecting circuits.
Is a switch and example of a resistor?
No it is not. A resistor has a known resistance that is less than infinity. A switch has a resistance of either infinity when it is open or low when it is closed

How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
Is graphite a high resistance or low resistance of electricity?
Graphite is low resistance of electricity...
What is a heater blower resistor?
Heater blower resistor is what controls the low medium high speeds...
What is ment by high resistance and low resistance on a meter?
On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.
Do meters usually have a high or low internal resistance?
It depends on the application. Voltmeters have a high internal resistance, while ammeters have a low internal resistance.
What is high resistance and low resistance?
Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.
