EM6 INTERNAL RESISTANCE AND EMF OF A BATTERY CELL DCP ASPECT 1 SYMBOLS: Internal resistance of the battery: r External variable resistor: R Voltage: V EMF of the battery: E Current: I FORMULA V= IR E = I (R+r) E = IR +I ⋅ r E = V + I ⋅ r V = E - I ⋅ r V = -r ⋅ I +E _Graph of V against I will be plotted in order to_ _determine the internal resistance and EMF of the battery. The slope will be -r and the intercept vertical axis will be the EMF (E)._ REFERENCE VALUE EMF of the battery

Experiment 7: Deflection of beams (Effect of beam length and width) 1. OBJECTIVE The objective of this laboratory experiment is to find the relationship between the deflection (y) at the centre of a simply supported beam and the span‚ width. 2. MATERIALS - APPARATUS Steel Beams‚ Deflection measuring device‚ 500g weight 3. INTRODUCTORY INFORMATION The deflection of a beam‚ y‚ will depend on many factors such as: - The applied load F (F=m•g). The span L. The width of the beam b‚ and

Write the equation of a line parallel to the given line but passing through the given point. y=1/2x+1; (4‚2) Locate the parallel Line by using the ordered pair (4‚2) Multiply ½ by x to come up with x/2 Now we have y = x/2 + 1 Let’s use the formula y = mx + b whereas m equals slope and equals the y-intercept. Right now we know that m = ½ when using the above formula So in order to find the equation which is parallel to y + 1/2(x + 1) the slopes will have to be equal. We must incorporate
