What is the relation between internal resistance and load resistance when current is constant in the circute?
The total resistance of a circuit is the sum of the supply's internal resistance and its load resistance, because they are in series with each other. This is true regardless of the magnitude of, or the variation in, the current.
Is a voltmeter a linear scale?
This is because the resistance is measured by applying a fixed voltage to the resistor and measuring the current. Since I = V/R, the current/resistance relation is non-linear.
Using Ohm's Law explain how voltage changes in relation to current assuming that resistance remains constant?
how do you use ohms law express conductance in terms of current and voltage?
What will happen when we change value of load resistance in transformer?
The secondary load current will change. This, in turn, will cause the primary current to change (the primary current being the phasor sum of the [IS (Np/Ns)] and the primary current (Io).
When the resistance is known as conductance?
Conductance is the reciprocal of resistance, representing how easily electric current can flow through a material. It is defined as the ratio of current (I) to voltage (V) and is measured in siemens (S). A higher conductance indicates lower resistance, meaning the material allows more current to pass through for a given voltage. Thus, when discussing conductance, one is effectively looking at the ease of current flow in relation to resistance.
How does voltage change in relation to current assuming that resistance remains constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
Who discovered the relation ship between electic current and resistance?

How does resistance affect a circuit?
Resistance in a circuit restricts the flow of electrical current, leading to a decrease in the overall current in the circuit. This results in a drop in voltage across the components in the circuit and the generation of heat as energy is dissipated due to the resistance. Increasing resistance can reduce the efficiency of the circuit by impacting the voltage and current levels.
How do the partial current behave in relation to the corresponding resistance value for parallel circuiting of resistors?
The ratio of current flow through individual branches of a parallel circuit is inversely proportional to the ratio of resistance of each branch.
What will happen when we change value of load resistance in transformer?
The secondary load current will change. This, in turn, will cause the primary current to change (the primary current being the phasor sum of the [IS (Np/Ns)] and the primary current (Io).

What is the relation between the amount of electric current passed and the heat produced?
The relation is:P = I2RWhere:I is the current (for example, in amperes)R is the resistance (for example, in ohms)P is the power (energy per second) converted from electrical energy to heat. If the current is in amperes and the resistance in ohms, then power is in watts (equal to joules/second).
How can you increase the current by utilizing the keyword "efficiency"?
To increase current using efficiency, you can optimize the components in the circuit to reduce energy loss and improve the flow of electricity. This can be done by using high-quality materials, minimizing resistance, and ensuring proper insulation to enhance the overall efficiency of the system.
