please i need the full answer with the steps

2. a. Find the equivalent resistance Reg for the resistor combination circuit provided in figure 4. 20 2 ww ww ww 18 2 200 92 ww Figure 4 b. A heater coil is made using a material of cross section 2.60x10-6m? and a resistivity of 5.00x100-m and voltage of 75 V is applied across the length of the wire. For this heater determine the following: i. If the coil dissipates 5000 W, what is its length? ii. If applying a voltage of 100 V produces the same power dissipation, determine the length of the wire. 3. a. For the DC circuit is shown in Figure 5, determaine the following: If i,-5A, find vi and iy If v,=3V, find ix and iy. i. ii. 200 300 +V1 - i, 1) 100 402 502 Figure 5 b. Three inductors of 20mH, 50mH and 75mH respectively, are connected together in a parallel combination with no mutual inductance between them. Calculate the total inductance of the parallel combination in millineries.
