What is the internal resistance of a new D battery with an emf of 1.5 V and a wire of negligible resistance is connected between the terminals of the battery a current of 27 A is produced?
"In short, it is 0.055555555555555555555555555555556OhmsYou can use ohms law to calculate this.You will use the formula: Resistance Equals Voltage Divided by Current.It is written: R=V/ISo use the numbers you provided, and the formula above.1.5 / 27 = 0.055555555555555555555555555555556"I dispute this answer. emf = I(R+r) is the actual equation u need. From this equation, u will find that V = emf - Ir. Ohm's law is not applicable for this situation. However I do think you will need a voltage to find the internal resistance.
Which parts of a human body have highest resistance?
The skin has the highest resistance in the human body, followed by bones and cartilage. This resistance helps protect the internal organs and structures from damage caused by external factors like friction, impact, and infection.
What is internal friction in liquid?
Internal friction in a liquid refers to the resistance encountered by the liquid molecules as they flow past each other. It is a measure of how easily the liquid can respond to external forces and deformations. Internal friction affects the viscosity of the liquid, with higher internal friction leading to higher viscosity.
Is pressure internal or external?
Pressure can be both internal and external. Internal pressure refers to the force exerted by a fluid within a closed system, while external pressure can be the force exerted by a substance or object outside of the system onto the system.
What is the definition of resistance to acceleration?
Inertia resists acceleration. Inertia resists a change in the state of motion of a particle or rigid body. For instance, in order for the state of motion of an object to change, there must be a net external force exerting on the object, which is defined as mass times acceleration. Resistance to this net external force would therefore have to resist the object's acceleration, and that is inertia.
What is the unit of measurement of internal resistance?
unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance
Does the Atlantic salmon have internal or external fertilization?
internal external not internal external not
A battery of emf 2V is connected to an external resistance which is equal to its internal resistance and then find potential difference across the external resistance?
As the source impedance is equal to load impedance, it is assumed that both the resistances are in series. This distributes the whole voltage equally between both the impedance. Hence the PD across external resistance will be 1V.
Is bearded dragons development internal or external?

How do you check if you have a internal resistor or a external resistor coil?
To determine if you have an internal or external resistor coil, you can visually inspect the ignition coil. An internal resistor coil will have the resistor built into the coil itself, making it more compact, while an external resistor coil will require a separate resistor component in the ignition circuit. Additionally, you can use a multimeter to measure the resistance; internal resistor coils typically have a higher primary resistance (around 1.5 to 3 ohms) compared to external resistor coils. Always refer to the vehicle's service manual for specific resistance values for accurate identification.
When Replacing 12v coil on 1998 Kubota engine wg750 could it have resistance type external wiring from coil to distributor or is resistance internal in coil?
A engine coil has a high internal resistance, the needing of a suplementar resistance may be advised to you by a car electrician, who works with such brand and model of your car.
Is a polar bear external or internal?
Is a salmon internal or external?
What are the recommended exercises for improving shoulder internal and external rotation?
Recommended exercises for improving shoulder internal rotation include the sleeper stretch and the cross-body stretch. For external rotation, exercises like the doorway stretch and the shoulder external rotation with a resistance band are beneficial.

Is a keyboard internal or a external devise?
External. Internal devices would be something like a CD Drive, while an external device is a keyboard or mouse for example.
