Maybe show a picture ? I don’t get the question .
Energy = power × time
1800 = 300 × time
time = 1800 ÷ 300 = 6 s
Hope it helped!
Th correct answer to this question would be, Insulator. Notice in the question it says "Material". The question is basically asking, What item resists the flow of and electric current. A resistor is a device that suppose to strain the electric current. And resistance is the measure of how well the material can conduct an electric charge. With all of that being stated, Insulator materials include paper, dry wood, rubber, glass, ect. Insulator products provides resistance.
Make sure you read the questions very carefully.
Answer:
I = 0.15 A
Explanation:
The question is "a lamp subjected to a continuous voltage of 12V , consumes a power of 1.8 W. The intensity of the current passing through the lamp is what"
Given that,
Power of the lamp, P = 1.8 W
Voltage, V = 12 V
We need to find the current through the lamp. The power of the lamp is given by :
So, the current through the lamp is 0.15 A.
Sensible heat involves change in temperature of a substance. As the name suggests, it is the heat one can feel or sensed. When a system exchange sensible heat, its volume, pressure and state do not change. The sensible heat can be measured with the help of thermometer. The other type of heat is latent heat which involves change in state of the substance.
