What is the controlling resistance that determines the amount of heat flow through a composite wall?
The thermal resistance of the material with the highest resistance in the composite wall determines the amount of heat flow. Heat flow is restricted by the material with the highest resistance, which is often the material with the lowest thermal conductivity in the composite wall.

What determines the flow of electricity along the path of least resistance?
Electricity flows along the path of least resistance due to Ohm's Law, which states that current will follow the path with the least resistance. This means that the flow of electricity is determined by the resistance of the material through which it is passing.
What is the Ohmic heating equation and how does it relate to the process of heating materials through electrical resistance?
The Ohmic heating equation describes how electrical resistance generates heat when current flows through a material. It relates to the process of heating materials by showing how the amount of heat produced is directly proportional to the electrical resistance and the square of the current passing through the material. This relationship helps in understanding and controlling the heating process in various applications, such as in electric stoves or industrial heating systems.
What determines how severe an electric shock will be?
The severity of an electric shock is determined by the amount of current that passes through the body, the path the current takes, and the duration of the shock. Factors such as voltage, resistance of the body, and individual health can also influence how severe the shock will be.
What forces are acting on a parachute as it falls through the air?
On a parachute falling through the air, the main forces acting are gravity pulling it downward and air resistance pushing against it. Gravity accelerates the parachute towards the ground, while air resistance, or drag, slows down its descent. The balance between these forces determines the speed at which the parachute falls.
What is the significance of surface resistance in the field of physics?
Surface resistance is a crucial concept in physics as it determines how easily electric current can flow through a material's surface. It is important in various applications such as electronics, superconductors, and materials science. Understanding surface resistance helps in designing efficient electrical circuits and developing advanced materials with specific conductivity properties.
The opposition to the movement of charges flowing through a material is called what?
The opposition to the movement of charges flowing through a material is called resistance. It is a property that determines how strongly a material resists the flow of electric current.
What determines the amount of electric current flow through a circuit?
voltage and resistance v=ir v=voltage i=current r=resistance in physics right now
When the bulb is the resistance what this tells about the resistance?
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.
What determines the current in each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
What determines the flow of electricity along the path of least resistance?

When a multimeter is set to measure resistance?
it determines how well the current flows through the wires. ANSWER: When there is no outside power connected to it. But some power is necessary to read the resistance so the meter battery will supply the current necessary to measure the IR drop and translate that to resistance
Why rotor contactor in external resistance of slipring motor connected in delta?
rotor contactor are used to cut the resistance in slip-ring motor connected through resistance box. resistance is proportional to torque. so by controlling rotor contactor resistance can be controlled and hence torque can be controlled. for more information check torque and speed characteristic of wound motor.
Why does the oscillation of a pendulum gradually slows down after a certain interval of time?
Energy is gradually lost, through air resistance, and resistance in the string.Energy is gradually lost, through air resistance, and resistance in the string.Energy is gradually lost, through air resistance, and resistance in the string.Energy is gradually lost, through air resistance, and resistance in the string.
What are seven consecutive composite numbers?
114 through 126 are all composite.
What is the difference between resistance and resistor?
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors
Is the numbers 6-49 prime or composite?
Numbers from 6 through 49 are prime and composite, but 6 and 49 are both composite
