The electric current For ball mill alicey023 The working efficiency directly affects the concentrator economic benefits of the beneficiation factories. Therefore improve the efficiency of the mill is very important. Generally speaking‚ the factors restricting the improvement of the efficiency as following: 1. The electric current For ball mill‚ enlarging the current is to increase the rotate speed. If the has high rotate speed‚ its work efficiency will be high. However‚ there is one notice:

ELECTRICITY (CLASS – X) QUESTIONS FOR PRACTICE 1. State the law that governs the strength of the current passing through a metallic conductor when a p.d is applied across its end. Illustrate this law graphically? 2. Why is an ammeter connected in series and voltmeter in parallel in a circuit? 3. In an experiment the current flowing through a resistor and potential difference across it are measured. The values are given below. Show that these values confirm Ohm’s Law and also find the resistance

other side of the lemon. The nail and penny must not touch. This is a single cell of a battery. The zinc nail and the copper penny are called electrodes. The lemon juice is called electrolyte. All batteries have a "+" and "-" terminal. Electric current is a flow of atomic particles called electrons. Certain materials ‚ called conductors‚ allow electrons to flow through them. Most metals (copper‚ iron) are good conductors of electricity. Electrons will flow from the "-" electrode of a battery
